How can I use my custom signer instead of using StoreType.unspecified?

[se]

I'm trying to use Azure's Trusted Signing Account to Sign my files (MSI, DLL, EXE etc.) but I haven't able to make it work.

What I'm trying to use it, I want to use a custom signer that signs with my own commands on every file. My current signing process is not working if i sign it externally (after MSI and EXE build is finished).

For example;

project.Signing += (file) => MyOwnSigner.Sign(file);

Is it possible to do this?

Found the solution. I have created a class named MSCustomSigner.

using System;
using WixSharp;

namespace MyNameSpace;

internal class MSCustomSigner : DigitalSignature
{
	public override int Apply(string fileToSign)
	{
		Console.WriteLine("Signing: " + fileToSign);
		var process = new System.Diagnostics.Process();
		process.StartInfo.FileName = "powershell.exe";
		process.StartInfo.Arguments = $"-ExecutionPolicy Bypass -File ../../scripts/Sign-File.ps1 -Target \"{fileToSign}\"";
		process.StartInfo.UseShellExecute = false;
		process.StartInfo.RedirectStandardOutput = true;
		process.StartInfo.RedirectStandardError = true;
		process.OutputDataReceived += (sender, args) => Console.WriteLine(args.Data);
		process.ErrorDataReceived += (sender, args) => Console.WriteLine(args.Data);
		process.StartInfo.CreateNoWindow = true;
		process.Start();
		process.WaitForExit(30000);
		Console.WriteLine($"Signing completed with exit code: {process.ExitCode}");
		if (process.ExitCode != 0) throw new Exception($"Signing failed for {fileToSign}");
		return 1;
	}
}

I have passed the class to the project and boostrapper.

var bootstrapper = new Bundle(PackageHelper.DisplayName)
{
	DigitalSignature = new MSCustomSigner()
};

// ... my other codes

var project = new ManagedProject(productName)
{
	SignAllFiles = true,
	DigitalSignature = new MSCustomSigner()
};

Excellent.
This is a great example of the Open Close principle but on te product level...
